' nd useful improvements in Closures,

oli-i nich the following is a specication.

Gur invention relates to an improved closure; particularly a closure for covering the openings of passages or ducts by which oil'can be supplied to machines to lubricate the inoif'ing parts of same. n object of our invention is to provide a closure which i simple in construction and capable ot being easily and cheaply manufactured; and which can be easily moved to aiiord access to the opening, and yet normally be held in closed position.

This objeit and other objects and advantages of our invention are set forth at length in thefollowing description, which is to be taken in connection with the accompanying drawings; and the characteristics ot our invent-ion are precisely defined in the appended claims. le do not wish, however; to be restricted to the exact structure disclosed herein but reserve the right to make changes as regards the shape, size and arrangement of the parts without departing from the spirit and scope of our invention as the same is indicated by the broad meanings of the terms in which the claims are expressed.

0n the drawings: Y

Figure l is a side view ot a closure according to our invention;

Figs. 2 and 3 are top and bottom views of same;

Fig. l is a sectional view taken longitudinally through a closure or'.' the type shown in Figs. l; 2 and 3. illustrating the latter mounted over the entrance to an oil duct; and

Fig. 5 is a top plan oi the structure shown in F ig. 4.

The same numerals identity the same parts throughout. n

The closure is indicated on the drawings lt has a flat body with a pair of spaced apart parallel arms 2 eX- tending from one end7 these arms being in line with the lateral edges and being perforated to provide lugs, whereby the closure can be mounted on a pivot pin and moved to open or closed position as desired. The upper tace ot the closure is flat but the lower face is recessed out somewhat to p i a space Jfor a ilat spring 8. This spring is held to the body by means of a rivet e, and extends Atroni the rivet at one end to the arms 2 at the other end, lying between the latter. This spring is curved adjacent the end between. the arms 2; that is at the end which is opposite the riveted end; and it is bent between the arms in the manner indicated in Fig. l, that is to say it is set so that when the closure is held in the position presented by Fig.' l the bent or curved end of the spring will extend across l the openings in arms 2 and prefthe edges ot erably adjacent the lower parts of these openings. When the closure is mounted in position with a pivot pin engaging the holes in the arms 2, the spring i will be disposed so as to rest on top of this pin and thus be put under stress, which makes it hold the opposite end of the closure down tight so as to cover the opening over which it is placed.

in practice, the part oit the machine with which the closure is used, the part being indicated at 5, is provided with a pair of perforated lugs 6. Adjacent these lugs and between same, is a recess 7 from the bottom of which leads a passage 8. The closure is mounted in position to cover the recess 7 by passing a pin 9 through the lugs 6 and the perforations in the arms 2; the end of the spring 3 opposite its riveted end, resting upon the top oi the pivot pin 9 and thus holding the closure down so as to cover the recess 7 entirely. Oil supplied to the recess 7 oit course runs down through the passage 8 to the moving parts ot the machine; and whenever the supply of oil is to be renewed, the operator merely lifts the closure with his thumb-nail, thus exposing the recess 7; and when the closure is released, the spring 3 forces it down again into covering position.

rlhe body of the closure is preferably cast in one piece and the spring 2 attached by riveting; the operation of riveting being very easy and enabling the closure to be quickly completed. This closure is especially designed for oil openings for' magnetos foi' internal combustion engines, but might be employed `ori-other constructions as well.

Having described oni1 invention, 'what we believe to be new and desire to secure and protect by Let-ters Patent of the United States is:

A closure for an oil opening, comprising ,e bodyY 'having Ya `pair of `arms spa-ced apart and extending peiallel to eachother from one end of the body, said ai'nis having peroietlons to ieceive :i pivot pin, the closure extending across Ithe edges of the openings therethrough.

yIn testimony whereof, we have signed our naines to this specification this 22nd day 20 of May, 1919.
